Agastache rugosa 'Golden Jubilee'

Korean Mint. Clump-forming, herbaceous perennial. The edible leaves have an aniseed flavour and the spikes of purple flowers, produced all summer and into autumn, are very attractive to bees. Compact gold and sweetly scented foliage. Needs sun and drainage. Easy to grow and quick to flower,  80-100cm
